To establish a profile of the causes of apparently unexplained SS in genetic ref erral center and evaluate the current referral system Methods This was a retrospective database survey on patients who were referred our clini cal genetic service from 1988-1998 primarily because of SS We retrieved the st udy population from our computer database using "short stature" as a search han dle and then studied the demographic, clinical and laboratory data from their me dical records Results Three hundred and fifty three subjects were referred for genetic evaluation of SS in 1988-1998 The mean age of referred subjects was 11 5 years and the female to male ratio was 7 6 All referrals had undergone cytogenetic studies to exclude chromosomal abnormal ities, 19% of girls with apparently unexplained short stature had Turner syndrom e; at least 47 9% of the study population were normal variants and 25% of the referrals had inadequate information for classification Conclusions Genetic investigation is essential in the management of patients with SS, especi ally for girls suspected of having Turner syndrome, in which growth hormone trea tment has shown to improve final height We also highlight the inherited causes of short stature, which were often misdiagnosed as benign familial short statur e, and discussed the drawbacks of the current referral 展开更多

目的探讨身材矮小患儿的病因分布及遗传学诊断。方法回顾性分析86例身材矮小患儿的病因分布及临床特征。结果 86例身材矮小患儿中,病因有6种,以特发性矮小症(ISS,41%)和生长激素缺乏症(GHD,29%)最常见,遗传性疾病(14%)次之。将遗传性疾... 目的探讨身材矮小患儿的病因分布及遗传学诊断。方法回顾性分析86例身材矮小患儿的病因分布及临床特征。结果 86例身材矮小患儿中,病因有6种,以特发性矮小症(ISS,41%)和生长激素缺乏症(GHD,29%)最常见,遗传性疾病(14%)次之。将遗传性疾病组与ISS组、GHD组比较显示,各组患儿就诊年龄、身高、出生身长、出生体重、父母身高及胰岛素样生长因子1(IGF-1)水平差异均无统计学意义(P>0.05),但遗传性疾病组身高距同年龄同性别个体身高第3百分位数的差值(ΔP3)和身高标准差评分(HtSDS)显著低于ISS组(P<0.05),但与GHD组相比差异无统计学意义(P>0.05)。对遗传性疾病组患儿的临床表现进行分析,显示不同遗传性疾病表型谱存在异质性及表型重叠性。结论 ISS、GHD和遗传性疾病是儿童身材矮小的主要病因。对存在严重身材矮小的患儿,在除外GHD外,有必要进一步行遗传学检查明确诊断。 展开更多

目的探讨儿童矮小症的遗传学病因。方法选取2017年1月—2020年10月因生长缓慢就诊的矮小症患儿为研究对象。行矮小相关基因的全外显子测序,对发现的可能的染色体片段拷贝数变异者进一步完善基因芯片检查,比较基因检测阳性与阴性组之间... 目的探讨儿童矮小症的遗传学病因。方法选取2017年1月—2020年10月因生长缓慢就诊的矮小症患儿为研究对象。行矮小相关基因的全外显子测序,对发现的可能的染色体片段拷贝数变异者进一步完善基因芯片检查,比较基因检测阳性与阴性组之间临床表型差异。结果共纳入186例矮小症患儿,中位年龄7.3(5.1~9.1)岁,男103例、女83例。共检测出69例阳性结果,阳性检出率37.1%。其中54例通过全外显子基因测序诊断,15例通过染色体微阵列分析诊断。二元logistic回归分析显示,特殊面容和骨骼发育异常是儿童矮小症基因检测结果阳性发生的预测因素(P均<0.05)。结论全外显子测序是检测儿童矮小症遗传病因的有效技术手段,伴有特殊面容和/或骨骼发育异常的患儿更可能检测到遗传病因。 展开更多
